I have a rescue dog as well, 10 year old terrier had just over a year, but think he was not treated well, not miss treated but very nervous, barks at everything, getting him better trained, but being 10 would think he is set in his way, I am disabled so got a mobility scooter so can take him for a decent walk, got a off road one so can take him to the park which has a wood in the middle and he loves it in there.
